Steal An Egg / Guide
Steal An Egg Alien Biome guide
Updated 11 November 2026
Official Steal An Egg Alien Biome times from the Roblox listing, what is confirmed, and an honest desk list of alien pets. No invented Speed or codes.
This page uses two layers, and they stay separate. Official facts come only from the public Roblox game page, the official event listings hosted by the group "“and Collect Rare Pets”", and the public group profile we could read without a login. Desk listings (pet names, a Speed figure, mutation notes) already exist on BloxDesk values, biomes and mutations pages. Those desk figures are not official patch notes. We do not invent missing numbers.
Official times
The developer group "“and Collect Rare Pets”" listed a public Roblox event titled "NEW ALIEN BIOME", with the subtitle "THE NEWEST BIOME IS HERE!". The official window starts on 7 November 2026 at 16:00 UTC and is listed until 14 November 2026 at 19:00 UTC. In Europe/Warsaw (CET, UTC+1) that is 7 November at 17:00 through 14 November at 20:00.
The same group listed a later event titled "Black Market Dealer!", subtitle "SLICK RICK IS COMING". That official window is 14 November 2026 at 15:00 UTC to 16 November 2026 at 17:00 UTC, which is 14 November at 16:00 through 16 November at 18:00 in Europe/Warsaw.
| Official listing | Official start (UTC) | Official end (UTC) | Europe/Warsaw | Source |
|---|---|---|---|---|
| NEW ALIEN BIOME (THE NEWEST BIOME IS HERE!) | 7 November 2026, 16:00 | 14 November 2026, 19:00 | 7 November, 17:00 to 14 November, 20:00 | Roblox event listing |
| Black Market Dealer! (SLICK RICK IS COMING) | 14 November 2026, 15:00 | 16 November 2026, 17:00 | 14 November, 16:00 to 16 November, 18:00 | Roblox event listing |
The Alien Biome listing end is the end of a public event card, not a confirmed date when the biome is removed. The official card does not say whether the biome stays after 14 November, 20:00 Europe/Warsaw. We leave that as unknown until a new official listing or game-page note says so.
A second official fact about the listing text: the event description we read on 11 November 2026 still includes the pre-launch sentence "A NEW ALIEN BIOME ARRIVES NEXT WEEK!". The subtitle and the start time say the biome is here. We quote that honestly and do not pretend the leftover sentence is a future date.
What the official listing actually says
The official Alien Biome description, hosted by "“and Collect Rare Pets”", is a short story, not a stat sheet. It says Paranoid Pete tried to warn everyone, his radar is picking up stronger signals of extraterrestrial activity, UFO sightings are becoming more frequent, and the aliens have set their sights on Steal An Egg. It does not name pets, it does not give a Speed number, it does not list mutations, and it does not mention a promo code.
The official Steal An Egg game page explains the loop that still applies in a new biome:
| Official how-to-play step | What it means for this biome |
|---|---|
| Steal eggs from pets | You still take eggs from nests, including rarer ones once you can reach them. |
| Hatch eggs to collect rare pets | New biome eggs, if you can carry them home, still hatch into pets for your pen. |
| Earn money from your pets | Income comes from pets that stay in your base, not from a player trade market. |
| Upgrade your treadmill and base | Speed and storage still come from those upgrades. |
| Train on the treadmill to gain Speed | Speed is the official way to reach rarer eggs. The official pages do not publish a number for this biome. |
| Steal eggs from other players | The official loop still includes taking eggs from other bases. Be fair and stay inside the game's own rules. |
| Discover rarer eggs, pets, sizes, and mutations | The game page confirms that sizes and mutations exist. It does not name Alien-only mutations. |
The public profile of the developer group had an empty description and an empty shout when we read it on 11 November 2026. Public social-link endpoints for the group and the universe required a Roblox login, so we could not confirm an official Discord, X or YouTube URL from those endpoints. This guide therefore does not invent those links, and it does not repeat patch notes that we only saw quoted on third-party sites.
How to reach and unlock the biome
Official pages confirm that you gain Speed by training on the treadmill, and that higher Speed helps you reach rarer eggs. They do not publish a step-by-step entrance, a quest checklist, or a Speed gate for the Alien Biome.
| Question | Official answer (with source) | Still unknown in official notes |
|---|---|---|
| When did the official window open? | 7 November 2026, 17:00 Europe/Warsaw (16:00 UTC), from the event listing. | The exact minute your server updated can differ if you stay in an old server. Rejoin if your world still looks unchanged. |
| How do I get ready? | Train Speed on the treadmill, upgrade your base, and play the official loop on the game page. | The exact Speed needed is not printed on the official listing or the official game description. |
| Is there a published Speed number? | No official number on the pages we could open. | The biomes table on the Steal An Egg hub lists a desk figure of 250B Speed for "Aliens", attributed to an in-game check by eggPing on 7 November 2026, not to an official post we can link. Treat 250B as a desk figure until an official source confirms it. |
| Does the biome leave on 14 November? | The official event card ends on 14 November 2026, 20:00 Europe/Warsaw. | Removal is not confirmed. |
If a sign inside the game shows a recommended Speed, read that sign in your own session. We are not inventing a gate here.
Alien pets on our values desk
The official event listing does not name the new pets. The names below already appear on our Steal An Egg values page (desk updated 9 November 2026). The values file attributes those Update rows to in-game captures checked by eggPing on 8 November 2026, not to an official Roblox listing. This table repeats the names and the desk grouping only, so you can jump to the income list. It does not copy income numbers into this guide, and it does not present those names as official patch text.
| Pet name on our values desk | Desk grouping (not official notes) | Official listing names this pet? |
|---|---|---|
| Bloomfin | Aliens biome | No, not in the official event text we read |
| Vexlet | Aliens biome | No |
| Bloomspire | Aliens biome | No |
| Glacigon | Aliens biome | No |
| Redmaw | Aliens biome | No |
| Aurora Stag | Aliens biome | No |
| Viridian Prowler | Aliens biome | No |
| Obsidian Rex | Aliens biome | No |
| Jellynova | Alien Tidal Surge | No |
| Flarefish | Alien Tidal Surge | No |
| Tideler | Alien Tidal Surge | No |
| Abyssjaw | Alien Tidal Surge | No |
| Prismare | Alien Tidal Surge | No |
| Nebuloth Kraken | Cosmic Eclipse fishing | No |
| Xenorath | Fusion Lab | No |
| Sproutling | Alien event | No (income also listed as Value unknown on the desk) |
| Rubyhorn Beetle | Crystal Egg | No |
| Jadefin Swordfish | Crystal Egg | No |
| Opal Emperor | Crystal Egg | No |
| Moonveil Lynx | Crystal Egg | No |
| Amber Minotaur | Crystal Egg | No |
| Sapphire Leviathan | Crystal Egg | No |
For dated base income, rarity and income band, open the values page and the income tier list. Those pages already label the figures as unofficial fan data. If a name is missing from an official post we can link later, we will keep the label honest.
Mutations
The official game description says you can discover mutations. It does not publish a multiplier table and it does not name Alien-only mutations.
Our mutations page (updated 9 November 2026) already lists older mutations from the community wiki, plus two newer rows that trackers tie to the Alien update:
| Mutation on our mutations desk | What the official pages say | What our desk currently notes (not official notes) |
|---|---|---|
| Mutations in general | The official game page says rarer eggs, pets, sizes and mutations exist. | Final income on the desk is described as base income times a mutation multiplier times a size multiplier. Those formulae are not official patch text. |
| Abducted | Not named on the official listing or game description we read. | Listed on our mutations page with an unofficial source note. Open that page for the dated figure. |
| Dark Matter | Not named on the official listing or game description we read. | Listed on our mutations page with an unofficial source note. Open that page for the dated figure. |
We do not repeat unofficial multipliers here, so a later official post cannot be mixed up with a fan number.
Codes and staying safe
The official game description does not mention a code or a redeem step. Our Steal An Egg codes page already explains that there is no public promo code and no redeem box that we can show. Strings from other egg or steal games will not become Alien Biome codes just because the names sound similar.
Real rewards in this game are claimed inside Roblox. Nobody needs your password, your email code or a file download to "unlock" an Alien pet. If a site or a video asks you to log in away from roblox.com, stop and close it. A parent or guardian can help if something feels off.
A number typed on a keypad inside a UFO or a vault, if you ever see one in the game, is a puzzle in the world. It is not a promo code for this page.
What official pages say about Slick Rick
The official "Black Market Dealer!" listing says a mysterious dealer called Slick Rick is coming to Steal An Egg, that nobody yet knows where he came from or what he is selling, and that he comes and goes when he pleases. That is all the official card confirms. We will not invent a shop list before 14 November 2026, 16:00 Europe/Warsaw.
FAQ
When did the Alien Biome start, and when does the official listing end?
The official Roblox event "NEW ALIEN BIOME" starts on 7 November 2026 at 17:00 Europe/Warsaw (16:00 UTC) and the public card is listed until 14 November 2026 at 20:00 Europe/Warsaw (19:00 UTC). Source: the official event listing.
Does the listing end mean the biome leaves the game?
No official text we could read says the biome is removed when the card ends. The end time is the end of the public listing. Whether the biome stays is unknown until a new official note says so.
How much Speed do I need for the Alien Biome?
The official game page says you train on the treadmill to gain Speed and use it to reach rarer eggs. It does not print a number for this biome. A 250B figure appears in the biomes table on the Steal An Egg hub, from an unofficial in-game check. We do not treat that as official.
Are there Steal An Egg codes for the Alien Biome?
The official game description does not list a code, and our codes page still has an empty official-style list. Ignore any "free Alien egg code" that wants a password or a login away from Roblox.
Which Alien pets are officially named?
None of the pet names in the table above appear in the official event description we read on 11 November 2026. The names are desk listings from our values page. Use that page for dated income figures, and treat a name as unofficial until an official post we can link names it.
What does Slick Rick sell?
The official "Black Market Dealer!" listing says nobody knows yet what he is selling. The official window starts on 14 November 2026 at 16:00 Europe/Warsaw. We will update only after official text or a check we can source.
Where should I go next on BloxDesk?
Start with the beginner guide if you are new, then the values and mutations pages for dated desk figures, the codes page for the empty official-style list, and Steal An Egg news for the official event cards.
